摘要:
The invention relates to a method for detecting a physiological state of a patient deviating from a reference physiological state, in which, after having determined, in each of Q frequency bands, R reference matrices PR q,r with qe[l...Q] and rє[1...R] which correspond to the reference physiological state, the following steps are repeated in a loop: carrying out measurements, in M time segments, of an electroencephalographic signal; filtering and centring the measurements in Q frequency bands to obtain and determine MxQ scaled matrices of spatial covariance; for each time segment m, calculating a deviation from the reference physiological state, and comparing each of the deviations from the reference physiological state to a predefined threshold. The invention also relates to a monitoring device applying said method.
摘要:
The invention relates to a method for measuring one or more diaphragmatic functional parameters, said method comprising the steps consisting of: - a) a stimulation step by which a stimulation of the diaphragm is provided to generate a movement of one or more parts of the diaphragm, - b) during the movement of said one or more parts of the diaphragm, imaging one or more parts of the diaphragm over time through an imaging step comprising the steps of emitting unfocused ultrasound waves, detecting ultrasound waves reflected and/or scattered by organic tissues, processing the reflected and/or scattered ultrasound waves over time to generate images by technical means, - c) processing, by technical means, images previously acquired during the imaging step to measure one or more movements of the diaphragm over time, and/or a propagation of a movement through the diaphragm over time, and/or a propagation speed of a movement through the diaphragm over time, and/or one or more movements of different parts of the diaphragm over time, and/or an amplitude of a movement of the diaphragm over time, and/or a time separating the stimulation of the diaphragm from the occurrence of a movement of the diaphragm associated to said stimulation, - d) based on one or more measurements of the processing step, determining one or more functional parameters of the diaphragm by technical means.
